Kalampaka and nearby Kastraki are the perfect areas if you wanna visit Meteora. Meteora is just amazing! A once in a lifetime experience.
I visited the monasteries, joined the sunset tour and also tried the half day rock climbing package with professional mountain guide lazaros botelis. It was a mixture of culture, history and eco-adventure. I personally prefer the little town of Kastraki because it has quaint provincial feel to it. The roads are small, houses with flowers, lovely little quiet town. Kalampaka is also beautiful but bigger and more accessible to commercial areas. So it really depends what you prefer. Both towns are very beautiful.
Very spiritual place in the Monastery's. The town seems to be hip and happening. The towering Forrest of stony outcrops is a must see for all travellers.
